Manhole

Abstract

A manhole is provided with a base plate, manhole walls, and a cover plate for covering the manhole. The manhole walls include of a plurality of grid-like wall elements arranged in rows one above the other and selectable from a modular system. A part of the grid-like wall elements has at least one conduit insertion opening so that the position, number, and size of conduit insertions into the manhole walls are freely selectable by arranging the grid-like wall elements. Several circumferential connecting frames are provided, which are arranged at different heights, and the grid-like wall elements are each connected on their top sides and bottom sides to one of the connecting frames.

1 . A manhole ( 1 ,  1 ′,  1 ″) comprises a base plate ( 2 ,  200 ,  201 ), manhole walls ( 3 ,  3 ′,  3 ″), and a cover plate ( 93 ,  93 ′,  93 ″) for covering the manhole ( 1 ,  1 ′,  1 ″), the manhole walls ( 3 ,  3 ′,  3 ″) including a plurality of grid-like wall elements ( 4 ,  5 ,  11 ;  401 ,  402 ,  403 ,  404 ) arranged in rows one above the other and selectable from a modular system, wherein a part of the grid-like wall elements ( 4 ,  5 ,  11 ;  401 ,  402 ,  403 ,  404 ) has at least one conduit insertion opening ( 33 ,  34 ,  35 ,  36 ,  37 ,  38 ;  431 ) so that the position, number, and size und of conduit insertions into the manhole walls ( 3 ) are freely selectable by arranging the grid-like wall elements ( 4 ,  5 ,  11 ;  401 ,  402 ,  403 ,  404 ), and wherein several circumferential connecting frames ( 20 ,  20 ′,  20 ″) are provided, which are arranged at different heights, and that the grid-like wall elements ( 4 ,  5 ,  11 ;  401 ,  402 ,  403 ,  404 ) are each connected on their top sides and bottom sides with one of the connecting frames ( 20 ,  20 ′,  20 ″). 
     
     
         2 . The manhole according to  claim 1 , wherein the grid-like wall elements ( 4 ,  5 ,  11 ;  401 ,  402 ,  403 ,  404 ) are connected with the connecting frames via fit connections. 
     
     
         3 . The manhole according to  claim 2 , wherein the grid-like wall elements ( 4 ,  5 ) each have fit connector ( 450 ,  451 ) on their top sides and bottom sides, which are fit into suitable fit receptacles ( 230 ,  231 ) of the connecting frames ( 20 ,  20 ,  20 ′″). 
     
     
         4 . The manhole according to  claim 3 , wherein the fit connectors ( 450 ,  451 ) are formed triangularly corrugated. 
     
     
         5 . The manhole according to  claim 3 , wherein the circumferential connecting frames ( 20 ′,  20 ″) comprise an H-cross-section with two flange walls ( 220 ,  221 ) and one web ( 222 ), wherein the flange walls ( 220 ,  221 ) form upper and lower fit receptacles ( 230 ,  231 ) separated by the web ( 222 ), wherein the fit connectors ( 450 ) of the grid-like wall element bottom side are fittable into the upper fit receptacle ( 230 ) and the fit connectors ( 451 ) of the grid-like wall element top side are fittable into the lower fit receptacle ( 231 ). 
     
     
         6 . The manhole according to  claim 5 , wherein a stiffening element is provided on the external flange wall ( 220 ) of the connecting frame ( 20 ″). 
     
     
         7 . The manhole according to  claim 6 , wherein the stiffening element is formed by a stiffening wall ( 223 ) arranged parallel with the external flange wall ( 220 ), which wall is connected to the external flange wall via a stiffening web ( 224 ). 
     
     
         8 . The manhole according to  claim 7 , wherein the stiffening web ( 224 ) is triangularly corrugated. 
     
     
         9 . The manhole according to  claim 1 , wherein the connecting frames ( 20 ′) are formed so that they can be assembled from several frame parts ( 202 ,  203 ,  204 ).
